ToriShogi is a small Shogi variant played on a 7x7 board.
The name "Tori Shogi" means "bird chess" and all the pieces are named
after birds. ToriShogi uses the same rules as shogi, except for
the pieces which are used and a few differences noted below.

These are the differences between Shogi and ToriShogi:

ToriShogi is played on a 7x7 board, with the last two ranks
being the promotion zone. This is the opening setup:

The Phoenix is the King in ToriShogi. It moves the same as a
King and the game is over when the Phoenix is checkmated or captured.

A piece must always promote when it enters or moves in the
promotion zone. Pieces remain unpromoted if dropped into the promotion zone, but must
promote the next time they are moved. Only the Falcon and Swallows promote in ToriShogi.

Swallows are similar to Pawns in Shogi. They may not be
dropped to give checkmate. They may not be dropped onto a column which already has two
unpromoted Swallows. (Shogi allows only one unpromoted pawn in a column.)

ToriShogi Pieces

An 'x' indicates a square which the piece may move or jump
to.

A dot is used to show jump moves clearly. It is the space
which is jumped over (but cannot be moved to).

A line indicates the piece may move any number of squares in
that direction.

A number indicates the piece may move in that direction up
to that number of squares, but not jumping.
